Topological Kondo Insulator from Spin Loop Currents
Andreas Gleis, Kevin Lucht, Po-Jui Chen +3
We demonstrate that interacting electrons in AB-stacked realize a topological Kondo insulator at hole filling per moiré unit cell. In the p…

Moiré-induced gapped phases in twisted nodal superconductors
Kevin P. Lucht, J. H. Pixley, Pavel A. Volkov
We demonstrate the emergence of gapped phases driven by the moiré superlattice that trivialize the topological states in twisted nodal superconductors. The effect arises from umkl…

Quantum geometric photocurrents of quasiparticles in superconductors
Daniel Kaplan, Kevin P. Lucht, Pavel A. Volkov +1
Nonlinear optical response is a sensitive probe of the geometry and symmetry of electronic Bloch states in solids. Here, we extend this notion to the Bogoliubiov-de-Gennes (BdG) qu…
